' mechanical movement for converting rotatory motion into a constant reciprocating mo ion.

In the accompanying drawings, Figure 1 represents a perspective view of the invention; Fig. 2 represents a horizontal sectional view; and Fig. 3 represents a detail pers ective view of the reciprocatin head or p ate.

Referring more particular y to the drawings, a drive shaft 1 is journaled in suitable bearings 2 and is adapted to project through a slot or elongated o ening 3 formed in a head or plate 4 which is slidably mounted in suitable guide-ways 5 arranged in standards on a base plate or supporting frame as shown.

On one side of the plate or head 4 is secureda laterally-projecting stud fi'on which a roller 7 is mounted: On the opposite side of the reciprocatin member 4 1s a stud 8 similar to stud 6 an having a roller 9 mount- .ed thereon. The rollers 7 and 9 of the studs 6 and 8 are disposed Within short distances of the adjacent opposite ends of the slot 3. Eixedly mounted on the shaft 1 adjacent to one side of the head or plate 4 are two oppositely-disposed heart-shaped cams or eccentrics 10 and 11, forming a cam member 10, the cams of which areadapted to alternately engage with therollers 7 of the studs 6 as the shaft'l revolves in one direction or the other. On the shaft 1 adjacent to the opposite side of the mounted a pair of oppositely-disposed heartshaped eccentrics or cams 12 and 13, forming another cam member 12 disposed on the shaft l'at right angles to the cam member 10 on the other side of the plate 4. The ends of the cams 12 and 13 are adapted to be alter nately brought into engagement with the roller 9 on the stud 8 when the shaft 1 is re volved On one or both ends of the plate or head 4 are secured connecting rods or links 14 by means of whichsaid head or plate 4 is con- 'nected to the mechanism to be driven.

suitable motive power may be applied to drive the shaft 1 in the desired direction, 7

thereby revolving the cams thereon, said cams being engaged with the rollers 7 and 9 on the opposite side of the fplate 4 will reciporth in the guideways 5, thus transforming the rotatory motion of the shaft into a constant or continuous reciprocating motion which is imparted through the connecting'rod 14 to the mech anism or machine to be operated. p

By arranging the heart-shaped cams as herein shown and described, the cams on one side or the other of the plate will be always in engagement with one or the other of the rollers 7 or 9, thus providing for the taking up of lost motion and imparting a steady even movement to the reciprocating member 4. In this embodiment of the invention, a crank arm 15 is shown to provide for the use of an other shaft and pulley if desired to cause the piston or plate 4 to work more smoothly.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

I claim as my invention 1. In a mechanical. movement the combination of a supporting frame, a reciproeating member mounted thereon, a rotary shaft ournaled on said frame, and two spaced cam members secured to said shaft at different angles to each other and arranged to engage and reciprocate said reciprocating member, said cam members being each composed of oppositely disposed heart-shaped cams.

2. In an apparatus of the class described, the combination of a supporting frame, a

reciprocating member mormted thereon, a

constant reciprocating motion to said memoppositely disposed heart-shaped cams and mounted on said shaft on either side of said reciprocating member, and means carried by said member on opposite sides thereof with which. said cams engage to impart a constant reciprocating movement thereto.

4,. ln aimcchanical movement comprising a suitably driven shalt, a reciprocating memher having formed therein a slot through which said shal't pmjocts, oppositely disposed hcart-shapml cams spaced from each other andarranged on said shal't adjacent each side of said reciprocating men'iber, and rollcrs arranged on opposite sides of said incinber in position to be alternately engaged by the oppositely disposed heart-shaped cams on each side of said member to impart a constant rcciprocating motion to the latter.

5. v: mechanimil movenumt comprising a suitably driven shaft, a reciprocating member, oppositely projecting heart-shaped cams mounted on said shaft adjacent to one side of said member, sin'iilarly disposed cams mounted on said shaft adjacent to the other side of said member, the lastanentioncd cams being arranged at right angles to the lirst-n'iontioned cams, rollers secured to the opposite sides of the plate and adapted to be alternately engaged by the oppositely projecting cams on each side ol said member to impart a reciprocating motion to said mend her, and a connecting rod secured on said reciprocating member.

6. A mechanical movement comprising a suitably driven shaft, guide-Ways arranged on opposite sides of said shaft, a reciprocating plate adapted to slide in said guide-Ways, said plate having formed therein a longitudinally disposed slot through which said shaft is adapted to project, oppositely-projecting heart-shaped cams mounted on said shaft adjacent to one side of said plate, similarly disposed cams mounted on said shaft adja-v cent to the other side of said plate, the last mentioned cams being arranged. at right angles to the first-mentioned cams, rollers secured to the opposite sides of the plate and adapted to be alternately engaged by the oppositely-projecting cams on each side of said plate to impart a reciprocating motion to said plate and a connecting rod secured to said plate.

In testimony whereof I have signed my name to this specification in presence of two Witnesses.
